Contribution of backbone dynamics to entropy changes occurring on oxidation of cytochrome b5. Can redox linked changes in hydrogen bond networks modulate reduction potentials?
Article Abstract:
Research was conducted to examine the changes in backbone dynamics that take place upon the oxidation of rat cytochrome b5 using model free analyses of 15N-relaxation rates of both oxidation states of the protein. An upper bound for the contribution of backbone dynamics to the entropy change related to oxidation was measured based on the observed changes. The magnitude and likely importance of entropic contributions to the electromotive force are analyzed based on the observations.
